Help please! I don't really get this.

Boxes from top to bottom

Sides

6

6

12

52

Step-by-step explanation:

1) Split the prism into individual sides.

2) Find the area of each side by multiplying length by height.

3) Add the areas together.

    Since this is a rectangular prism; the top & bottom of the box will have the same area. Same with the other sides.

    The top of the box is 2 by 3 making the area 6 times 2 for the bottom is 12

    The left and right sides are 3 by 4  A = 12 times 2    24

    The front and back are 2 by 4  A=8 times 2              16

    24 + 16 + 12

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
